Worth Four Dot

The worth four dot test is a great tool to help the clinician understand what the patient sees with each eye. This test is useful for detecting double vision or suppression, in which the brain ignores visual signals from one eye.

For what purpose is it used?

This test provides our eye doctor with information about how your brain processes the visual information it receives. Is your brain able to pay attention to both eyes at the same time? Or is it suppressing or selectively filtering out the information that's coming from one of the eyes? In this case, it allows your doctor to determine if you are neglecting the left or right eye. Or are you alternating back and forth between the eyes that are being ignored? Or do you exhibit a double vision response at times?

Another benefit of this test is that it gives our eye doctor information about how deeply embedded a suppression may be or what distances you may be experiencing double vision at. This is very helpful when they are working with you in the vision therapy room to customize procedures to help make you better.

What is suppression of one eye?

It occurs when one eye is given preference over the other by the brain by ignoring the visual signal from one eye and paying attention only to the other. The purpose of this is to prevent double or blurry vision. The brain does this when the eyes are not working together properly, but vision therapy can help train our brains to learn how to work correctly with both eyes.

What are the possible outcomes of a worth four dot test?

When Dr. McBryar uses the worth four dot test she will have the patient look at the worth for dot flashlight. The flashlight has four dots, one red, two green and one white. Then she will ask you to wear these red and green glasses, with the red lense covering your right eye. Dr. McBryar will be able to learn more about how your vision is working, how deep your suppression is embedded and at what distances you are experiencing double vision.

Two red dots: If you were to look with the right eye and the left eye was suppressed, what you would see would be the two red lights.

Three green dots: If your right eye is suppressed or ignored, you will see three green dots and the fourth will not be visible.

Five dots: If you have double vision, then you would see five dots, two red dots from your right eye and three green dots from your left eye.

Four dots: If there is proper fusion between both eyes, then you should see four dots.

Testimonials

Vision therapy is well worth the response, time and effort. Our Son had a hard time focusing and writing neatly. After vision therapy Seth could complete a task in half the time if previously took. His abilities to focus improved greatly and so did his handwriting.

Also, he was better at listening. As a parent, we wanted learning to be fun for our Son, and vision therapy made this possible.

Dr. McBryar , Kristen and John are all marvelous and we would recommend them to anyone I only wish that we would have found them sooner!

Prior to coming to the institute for vision development my son complained of daily headaches. Therapy has eliminated his headaches completely. I love knowing my son is able to learn pain-free for the rest of his life because of the work that has been done over just a few weeks in this office. He he absolutely loved coming that didn't even feel like going to a doctor or therapy. We are grateful for the relief he was able to find by coming here.

Thank you!

When we first came to the practice, my son did not have huge issues, but lots of small ones- trouble with reading, sports (hitting the baseball consistently), coordination, etc- that were not easily detectable,but when put together presented issues. The staff here were all very professional and loving towards him. While I was concerned in the reading, my son was concerned with the athletic side. Seeing improvement night off the bat gave him confidence that i have nor seen in him and made him want to not only Come to therapy, but also made him want to work hard. He has surpassed his grade level and above in reading and hit his first home run this year! Thank you!!!
